The Castro brothers won’t be crashing together in the nation’s capital.

Incoming Housing and Urban Development Secretary Julián Castro, easily confirmed Wednesday by the Senate, has plans to find his own residence in the Washington area for himself and his growing family. And besides, his twin brother Joaquín, a freshman Texas Democratic congressman, said he doesn’t quite have the space anyway.

“He’s bringing his family up so they’re leasing a place somewhere, trying to decide where to lease a place. He’s got his wife and his daughter, and they’re expecting another baby,” Rep. Joaquín Castro told POLITICO Wednesday afternoon, just minutes after the Senate voted 71-26 to add his brother to the Obama administration. “So I have my 520-square-foot condo. Kind of small for more than one person.”

But Rep. Castro said he still hopes to have frequent visits with his brother once the family moves to Washington, although the twin brothers will have very different work schedules.

“My life has been going back and forth. His life will be different in that he’ll be in Washington frequently,” said Rep. Castro, who represents the San Antonio area where his brother has been serving as mayor.

Rep. Castro also said he wasn’t worried that his brother’s fast-rising political career could be jeopardized by outside forces — a phenomenon often dubbed the “Cabinet curse” — that befell former Obama officials Kathleen Sebelius at the department of Health and Human Services and Steven Chu at the Department of Energy.

“I think you have to focus on the task at hand,” Rep. Castro said. “My brother has always been good at doing the job that he’s been tasked with. I think that’s what you’ll see him do. He’s out of partisan politics. Well, technically, he’s never been in partisan politics because he’s a mayor and it’s nonpartisan. But he’s out of partisan politics and he’s focused on doing the job at HUD.”

Rep. Castro also welcomed the confirmation vote, which drew support from more than a dozen Republicans.

“It was great to see that it was bipartisan support for my brother’s nomination,” Rep. Castro said. “A lot of the issues that they deal with in HUD are not partisan issues: making homeownership more affordable and accessible, combating homelessness. So it was great to see and I think he ought to do a great job for the country.”
